I agree that we should not forbid someone to add a particular ID to an observation, but, as an identifier, forbidding me to “agree” with an ID better than mine would not make me feel incomfortable. If an ID better than mine comes next, either I do nothing (if it’s refining my ID) or I withdraw my ID (if it’s disagreeing with it and I have no clear reason to think I am right).
Not making an observation RG too soon is a major concern for me. It’s more valuable if someone else comes later and review the observation.
I don’t intend to learn from every observation/ID. It is more than enough if I can ID at the rank tribe and I need not learn all species in the tribe (and I would like to disable notifications of refining IDs).
I like to see an expert confirm my ID. I like to confirm the ID of an expert after I learnt (and then to ID similar observations, as it happened for Senna weddelliana (short story)). But if an expert disagrees with my wrong ID, in most cases, I have no motivation to confirm the expert’s ID.
